This is a high-grade classroom material video. This is better than people at university will teach you.
Thank you for watching!
Been working in a Data center for 10 years. I feel I've learned way more in this video than I have my whole time onsite. :/
Thanks for the comments, thanks for watching.
I was thinking the same exact same thing I wasn’t a dc tech but i was the sme for my team that worked with DC Team
Friends, we have to support these kinds of efforts. This channel is so informative and beautifully illustrated. I hope you all are learning as much as I do. Thanks!
Thank you so much 😀
OUSTANDING!! I am IMPRESSED. I've viewed LOTS OF RUclips tutorials over the years (literally hundreds),... and you are LIGHT YEARS AHEAD OF ALL OF THE OTHERS! (in my humble opinion) You speak "ENGLISH" and you are CLEARLY VERY KNOWLEDGEABLE AND VERY THOROUGH! Thank you sir! YOU ARE GIFT TO IT PROFESSIONALS!
Thank you for the kind words, we are working hard on doing a respectable job of presentation and at the same time engaging our viewers. We do make mistakes and our great viewers call us out, and we want that feedback. We hope you will come back for more!
Thanks for publishing this video. I hadn’t realised how far networking has advanced since I did a final year undergrad dissertation on ATM switches about 25 years ago! I feel all caught up now 😊 👍
Thanks for sharing!
This is the best overview of fibre standards that I have found. It's just the information I needed for choosing equipment for my new house. Thanks.
Thanks for watching!
This is the best video I've seen on fiber optics.
Thank you for watching!
This video has helped me understand different types of optics and what they are used for. Thank you Lowell.
Glad to help
That is the very clearest and most informative introduction to fiber optics I have seen. Thank you very much for making it.
Glad it was helpful!
AMAZING video!! Started in IT in '97 and in 30mins you succinctly and eloquently detailed what took me well over a decade to learn. Truly excellent work!!
Glad you enjoyed it!
Overall this is a really informative video. Great for getting someone up to speed with fiber. One thing though, there is a difference between path loss and return loss. Path loss (including intrinsic losses) is the attenuation of the signal down the path between the transmitter and receiver. Return loss is the value of how much light is reflected back to the source. They are very different things. Great work. I look forward to watching more of your videos.
Thanks for the input and comments, it is always appreciated!
I’m astonished as to the amount of information I got from this video. Very informative and easy to follow. I admire your work
So glad you enjoyed and found it beneficial. Thanks for the comments and for watching.
100%, learned as much as a 3 day course to get fiber optic installer certified
Tons of information in half an hour . So great . Thank you
Thanks for watching!
The best video on fiber cables. this one video on finer cables/transceivers is more than enough to work in a data centre and crack interviews.
rk: there is much more to learn in working for data centers, storage fabric, TOR systems, VLANs, server management, routing within and without the data center, Software Define Networks, virtualization on Windows, Linux and VMware, SANs, cluster systems, WAN interfaces, and so much more! Thanks for watching!
Incredible overview, clear and to the point. I've pointed my coworkers to it. We had no idea that 400Gb/s is now possible.
Thanks for watching!
this is really amazing! so comprehensive, made my understanding of the whole ecosystem so easy! Super effort by producer, really grateful!!
Thanks for watching!
Amazing video! This has more information in single 30 videos, that dozen other videos and articles I saw before. Combined. Good job. This is the goto video on fiber optics. Very comprehensive.
Glad you enjoyed it!
Nice video Sir. One of my tutors gave me a downloaded version of this video 6 days ago. I just had to find you! This page is quite an asset. Kudos Sir.
Welcome aboard!
I watched today other video of yours, when i was searching for fiber explanations i found your video, and immediately i thought: ohh this is going to be very detailed and explained. Aaaaand it was ;) Thank you so much for such great videos ! Thank god there are still people like you and make proper explanation rather than : 'fc , connectors in 1 minutes.. ' ;)
Glad it was helpful!
Mr V, am an IT student and this video was very resourceful. Well i have been watching these videos for IT knowledge
Welcome, this channel is for you!!
This is by far one of the most underrated IT videos of all time. Incredible. If there was a tip button, I literally would've sent money. Thank you so much for sharing!!!
Thank you for the kind words, we hope you will come back!
It’s your lucky day because there is a tip button now!
As an Ops technician at a data center in Maryland I've got to say this was hands down the best video I've ever seen on the subject. Everything you mentioned and showed are exactly what I see and work with everyday.
Thank you!!! And thanks for watching and taking the time to comment.
I'm going to say what most of the comments are saying. I've learned more in this video than I have researching google and blog posts for years. Fiber is one of those dark arts because of all the different types. But this video put it in a super easy format and explained everything. All in 30 minutes. Thank you.
Nonya, thanks for the comment. This is a subject that is difficult to find good information unless you work in this industry. We are working on bringing this information and understanding to more folks.
I work for a major logistics company for Google. I see fiber cables, optical modules, network switches, etc. all day long. It was only after watching this video did I even begin to understand what this material was, how it is implemented, and what I had to understand if I wanted to work in the nearby Google data center. Thank you!
Thanks for the comment and for watching!
Fantastic video, will have to play in slo-mo just to digest the knowledge shared. Many Many thanks
Glad you enjoyed it!
I learned more here than I did in school. Thank you.
Thanks for watching!
This video is the best education on fiber to have been publicly published. Great video. Great production.
Glad it was helpful!
Super good prez at super pace. Thanks on the effort and the gift.
Glad you like it!
Thank you so much for sharing the knowledge. It's much appreciated for us beginners

This is priceless, a very comprehensive overview.
Thank you for the comment!
Outstanding breakdown.. Amazing..
Thanks for watching!
Fantastic video! This video brings everything about fiber and LAN technologies together in an interesting and easy to understand method. I can't tell you how much I enjoyed the video. However, you misspoke at 6:06; 850nm is not a lower frequency, it is a lower wavelength but higher frequency than say 1300nm.
You are correct!!! Keep us honest! Thanks for the comment and for watching!
Great video!! Much appreciated😀
My pleasure!
Thank you for this detailed education. I have learned not to watch these videos on my tiny cell phone because I want to catch every piece of wording.
The videos are produced with a computer screen in mind, thanks for watching!
the best video on Fiber optics!
Glad you enjoyed it
Great run through. Really helpful

Great video!! Much appreciated
Glad you enjoyed it!
Finally a video that tells me what I needed to know! What fiber to pre-wire my new house with?... Looks like OM3 should work fine! I won't have anything even close to 100M.
Thanks for watching!
actually you would be well advised to use OS2 single mode cabling. That will allow you to move the signal from your FTTH connection to anywhere in the house and the extra cost of transceivers is trivial. Also OS2 is now cheaper than OM cabling of any grade.
That said, cat 6a is fine for housing. Just put in empty tubing so you can pull the fiber cable if you should ever need to do so.
Amazing video, thanks.
Thanks for watching!
Sir I really appreciate your help.
It's my pleasure

Thanks for the comment and for watching!
Small correction: a plenum is an air _circulation_ space. If air doesn't normally flow through it, it's not a plenum. The drop ceiling in most commercial structures is a plenum as it's the return path for HVAC systems. In residential settings, most setups have ducted returns. (In my parents house, the space under the stairs is a plenum as the return duct is open to the back of the stairs, vs. ducts run all the way to the registers. In my house, there are two large ducts leading to filtered registers, one in a wall, the other in a ceiling.)
Note: I had this very conversation with engineers, architects, and city inspectors w.r.t. a computer room ("data center"). We had to have revised plans _explicitly_ stating the area above the ceiling was NOT a plenum. Yes, HVAC ducts pass through the space, but there is no air moving in the space; the room is otherwise vapor sealed. (this was but one of the many nits picked with the city.)
Thanks for the comment and correction, I believe you are correct as I reflect.
Eccellent! Too many times I've had to argue with folks what a plenum is!
Regarding 40 Gigabit in the chart at 5:03, there is one additional option, beyond the singlemode and MTP/MPO options: 40GBASE-SR-BD (or 40GBASE-SR-BiDi, short for Bi-Directional) uses the same kind of two-strand multimode cable used with 10GBASE-SR, but gives you 40 Gigabit Ethernet.
With 40GBASE-SR4, you have an MTP/MPO-12 connector carrying 8 10Gbps wavelengths (four in each direction). With the 40GBASE-SR-BD, the transceiver combines the 10Gbps "lanes" into two 20Gbps lanes, sending each out over the two fiber strands. That's where the bi-directional part comes in: In each strand, you have 20Gbps wavelengths traveling in each direction.
Although the length limitations for 40GBASE-SR-BD are lower than those of 10GBASE-SR, this is a great way to upgrade from 10 Gigabit to 40 Gigabit without needing to replace fiber. That's probably why, if you order a 40GBASE-SR-BD transceiver today, it'll take several months to arrive!

Thank you for watching!
thank you
You're welcome
Great video!
Glad you enjoyed it
came in here just to get a crash course in fiber optics and got a phd. great presentation
Thanks for watching!!!!
Work work with number 5 ESS electronic switching systems that incorporated fiber optics for the very first time in communication that's the Baseline for the internet that's how it all started AT&T Bell Labs is responsible for all of that great company great career God Bless America
Central Offices are making a come back as they reinvent how to provide edge services to the mega-internet services. The CO was the heart of the telecommunication world for years.
great content
Thanks for watching!
very nice... i am learning Adva now
Thanks for watching!
Thanks alot really for your time and effort just to make this video , i know im asking kinda much but can you make video how dose isps or government's deploy fiberoptic to the home ? In detail please ?.
I will consider the video, many cable companies are using fiber on the back end already and only use coax to the home. Thanks for watching!
nice tutorial
Glad you liked it!
